Images for exact Ruby and Node versions

[thisismydesign]

Hey, I've been looking for something like this since forever and your project looks promising. However, most projects I work with pin exact versions, such as Ruby 3.0.3 and Node 16.13.0. Would it be possible to build against a matrix of exact versions of Ruby and Node?

I guess the issue with this is the same as the reason I'm here: building custom versions together. Your Dockerfile for alpine grabs node from the alpine package manager without specifying the version:

docker-ruby-node/3.0/16/alpine/Dockerfile

Lines 7 to 11 in fec0ad0

	RUN apk -U upgrade \
	&& apk add --repository https://dl-cdn.alpinelinux.org/alpine/edge/main/ --no-cache \
	nodejs \
	npm \
	yarn

Because they don't keep previous versions of the packages in their repo, if a new Ruby version comes out it's not possible this way to build images for all the old versions of node.

Looks like I answered my own question here but if you were to support this somehow, that would be awesome :)

Hi,
sorry for the late reply.
I'll leave this open as a suggestion of this can be done without complicating the build process even more.
